FIGURE 2.

Graphical representation of the experimental protocol. Intervention of 12-wk supervised low-impact resistance exercise performed four times per week in the exercise group or habitual physical activity in control group. Strength of hip and shoulder abduction and flexion peak torque, balance, and flexibility were familiarized <2 wk before baseline (WK0) data collection. Strength, balance, and flexibility, as well as body composition measures of weight and waist, muscle thickness via ultrasound, and lean mass and % body fat from DXA, were collected at WK0 then at weeks 4 (WK4), 8 (WK8), and 12 (WK12). Blood samples collected for total cholesterol, total triglycerides, and HbA_1c analysis as well as questionnaires for quality of life (SF-36), sleep quality (PSQI), and enjoyment of exercise were collected at WK0 and WK12. Accelerometers recorded 7 d of physical activity during WK0 and WK12. *indicates measurement in the exercise group only at time point.
